Title: Improvements in or relating to frequency filters
IPC: H01P1/209
Filed: 1954-07-23
Abstract: 752,726. Filters. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 23, 1954 [July 24, 1953], No. 21568/54. Class 40 (8). A frequency filter comprises a guide G1 having an inlet I and an outlet U connected without reflection to a receiver O, and a guide G2 coupled to the guide G1 by a directional coupling R. An attenuator V is so adjusted that the amplitudes of the waves A1, C1, which are out of phase at certain frequencies, are equal for at least one frequency. The central wall of the guide G2 may be omitted to provide a cavity. In a modification, Fig. 2, the attenuator may be replaced by a guide G3 connected to a receiver 02. Thus energy fed to the receiver O1 is suppressed in a small frequency band, while energy is transmitted to the receiver 02 in this small band.

Title: Carburetters for internal combustion engines
Inventor: SWATMAN PETER PHILLIMORE
IPC: F02M7/17
Filed: 1969-04-29
Abstract: 1278291 Spray carburetters BRITISH MOTOR CORP Ltd 1 July 1970 [29 April 1969 21669/69 Heading F1B The carburetter of Specification 1223921 is modified by the provision of a flexible cord or tape 22 connecting the pressure-responsive diaphragm 16 to the choke control member 12. The cord or tape 22 is tensioned by a spiral spring 28 between the member 12 and its housing 14, the spring also loading the diaphragm 16 against atmospheric pressure. The tape 22 is fixed by a pin 25 and a clip 24 to a drum 23 on the member 12. The drum 23 may be contoured to provide for a decreasing movement ratio between needle and choke member movement on opening of the choke. In a twin-choke carburetter, Fig.4 4 (not shown) the respective choke members (12A, 12B) are connected to the opposite ends of a flexible strip (31). The strip (31) has a horizontal-portion on a member (32) clamped between parts of a guide (33) fixed to the diaphragm (16) and sliding in bushes (34) in a bore (35) in the carburetter body. Respective fuel metering needles (6A, 6B) are carried by the strip support member (32). The tape may be stainless steel, beryllium-copper or non-stretch plastics and the cord fine metal wires or polyester fibres. A single choke member 12 may be operated by a pair of cords or tapes connected to pulleys or drums at opposite ends of the member, the vertical runs of the cords or tapes being connected to a horizontal member carrying the metering needle 6.

Title: Improvements in or relating to metering equipment using magnetic drum
Inventor: AMBROSINO FRANCESCO
IPC: H04M3/08
Filed: 1961-06-15
Abstract: 950,988. Electrical calculating apparatus. STANDARD TELEPHONES & CABLES Ltd. June 8, 1962 [June 15, 1961], No. 21674/61. Headings G4A and G4C. [Also in Division H4] A magnetic drum, especially for use in metering telephone calls in the manner described in Specification 902, 401, is provided with routine testing means effective at every revolution of the drum without disturbance to the normal use of the related equipment. The basic system has ten tracks each dealing with the metering totals of 100 subscribers. The existing total of a particular subscriber is read out at RA and unity is added at AD. If a metering pulse has occurred on the subscriber's line since the total was last read gate RWG is opened to enter the new total in the manner described in the earlier Specification. A "chalk mark" A is also entered, being removed at the next revolution. If no metering pulse has occurred, RWG remains closed and the total is unaltered. A "chalk mark" B is entered when a metering total passes from 9999 to 0000 and is erased at readout. A parity bit is entered if the number of binary "1"s is even. Routine testing is effected by circuit RTC. In addition to the word positions for 100 subscribers each track has an additional ten word positions. A circuit (not shown) generates the number 9998 which is entered into word position 102 of the oddnumbered tracks in turn, no parity bit being inserted. Adder AD should now add 1 to produce 9999 which is entered in word position 102 on the adjacent even track with a parity bit and a "chalk mark" A. Comparison is made between the output of RWG and the output of AD. The absence of a "chalk mark" B is also checked. At the next cycle circuit AD should produce 0000 which is not written on the drum because of the "chalk mark" A. Instead the output of AD is tested for existence of "chalk marks" A and B and 0000 with proper parity. Erasure of the first test word is also checked. A second test involves writing 0000 into word position 103 of all tracks with wrong parity and "chalk mark" B. A permanent meter condition is given during this test on lead L1 and a "chalk mark" A entered on alternate tracks should prevent this condition opening RWG on these tracks. Failure of any check brings up an alarm.

Abstract: 1,208,366. Covering cores by winding. BURLINGTON INDUSTRIES Inc. 8 May, 1968 [25 May, 1967], No. 21745/68. Heading B8G. [Also in Division D1] Apparatus for joining ends of yarn without knotting comprises a housing, a drum member rotatably mounted on said housing, means for rotating said drum member, a passageway formed through the axis of said drum member for receiving overlapping ends of yarn in parallel side by side relationship, means carried by said drum member for receiving a supply of wrapping thread, and a thread passageway in said drum member having a discharge opening closely adjacent to but radially offset from the axis of the drum member, whereby on rotation of the drum member and axial movement of the yarns, high torque is applied to the wrapping thread as the latter passes around the overlapped yam ends. As shown, a housing 24 comprises two end members 26, 30 and a central member 28 which is apertured to accommodate a battery and a motor powered thereby for driving a friction wheel which engages the periphery of a drum member 50 having an axial stub shaft portion journalled in the upper part of member 28. Member 50 and the stub shaft are formed with a radial slot 64 which enters an axial passageway 66 formed in member 50 and the stub shaft. Member 50 is also formed with a cavity in which a thread spool is mounted on a stud 78 to rotate against the friction caused by a spring mounted on stud 78 between the spool and the inner end of said cavity. The thread 74 from the spool issues from an opening 84 in one end face of member 50 adjacent passageway 66. In operation, the motor rotates member 50, whereby the thread 74 issuing from opening 84 is wrapped around yarn ends E, E<SP>1</SP> overlapped side by side in passageway 66 and drawn axially therethrough. The join is then removed from the apparatus and the projecting tail ends are cut-off. In a modification, the drum member is releasably mounted between a pair of rollers, one of which is carried by a bracket fixed to the housing and the other one of which is carried by a bracket pivoted to the housing and spring biased towards the drum member. A knife blade for severing the tail ends is provided on the housing. In a further modification, the housing carries a pair of posts located one on each end of the drum member and provided with respective tailsevering blades aligned with the axial passageway.

Abstract: 583,630. Valve generating circuits. JELONEK, Z. Nov. 9, 1944, No. 22123. [Class 40 (v)] A pulse generator comprises a multi-electrode valve with the control grid and cathode associated in a circuit producing sustained oscillations which overcome biassing means to allow space current to flow during part of each positive half-cycle only, and with a coupling between the screen and suppressor grids to restrict the flow of anode current further and produce a short asymmetric pulse. The Figure shows a. conventional Hartley oscillator circuit connected between control grid and cathode. of valve V1 with network C1, R1 producing a mean bias beyond cut-off level. Capacitor C3 provides a transitron coupling' between the screen and suppressor grids which diverts space current from the anode to the screen during the conduction period to produce a short asymmetric pulse in the anode circuit, which may be tuned to a harmonic. Alternatively, the oscillator circuit may be crystal controlled. Specification 579,744 is referred to.
